Problema Solution
The prevalence rate of Hypertension among US adults is 30%. We plan to draw a random sample of 65 people from that population. What is the standard error of the sample proportion of hypertension?
Answer provided by our tutors
Standard Error:
SEp = sqrt [ p ( 1 - p) / n]
where,
p is Proportion of successes in the sample,
n is Number of observations in the sample
In our case we have:
p = 0.30 or 30%
n = 65 people
SE = (0.30(1 - 0.30)/65)^0.5
SE = 0.056839856
